1. A battery pack powered robotic device comprising:
a housing;
a plurality of wheels connected to the housing;
a motor configured to drive the plurality of wheels;
a battery pack receiving interface on the housing and configured to receive at least one battery pack for powering the robotic device, wherein the battery pack receiving interface is configured to interface the robotic device with a plurality of different types of battery packs, wherein the battery pack receiving interface is configured to interface the robotic device with at least one of a first battery pack of the plurality of different types of battery packs having a nominal voltage of 18 volts (V) and a battery capacity of between 3 ampere-hours (Ah) and 15 Ah, a second battery pack of the plurality of different types of battery packs having a nominal voltage of 12 V and a battery capacity of between 1.5 Ah and 15 Ah, a third battery pack of the plurality of different types of battery packs having a nominal voltage of between 70 V and 120 V and a battery capacity of between 3 Ah and 15 Ah, and a fourth battery pack of the plurality of different types of battery packs having a nominal voltage of between 70 V and 120 V and a battery capacity of between 3 Ah and 30 Ah;
a wireless communications module configured to receive a control signal from an external device;
a controllable arm including one or more joints and a clamping device, the one or more joints configured to articulate the controllable arm, the clamping device configured to clamp an object; and
a controller configured to:
receive the control signal from the external device,
determine whether to articulate the controllable arm or drive the motor of the plurality of wheels based on the control signal from the external device, and
articulate, in response to the control signal, the controllable arm to clamp the object with the clamping device.
